allowaccess fgfm and Port 541

So we use a FortiManager to manage all our remote firewalls. To enable the manager access to the remote fortigates you have to enable fgfm-access in the interface that it will be connecting to. When you do this, it open up port 541. All other management interfaces (ssh http/https telnet ping snmp) get restricted to trusted hosts, but fgfm-access gets opened up to the whole internet. Now the port is secure, but auditors freak out and customers don' t understand. Does anyone have any idea if there is a way to make this port appear as closed on a port scan instead of open? The best i have come up with is something like this: config firewall local-in-policy edit 2 set intf " port7" set srcaddr " Test_Public" set dstaddr " all" set service " FortiManager_541" set schedule " always" set action accept next edit 1 set intf " port7" set srcaddr " all" set dstaddr " all" set service " FortiManager_541" set schedule " always" set action deny next end This at least changes the state to filtered on a port scan. Let me know if anyone has any ideas.
